Description

Automatic board device that opens and shuts of compound carton

Technical Field

The invention relates to a carton opening and closing plate device, in particular to a compound carton automatic opening and closing plate device.

Background

At present, when a manufacturer encapsulates a processed and formed product, an automatic box opening machine and an automatic box sealing machine are adopted for processing, when the carton packaging machine is used, a folded carton is opened and sealed by the automatic box opening machine, and then the carton packaging machine is conveyed to a packaging station, and an operator loads the product into the carton; after the products are packaged, the paper boxes are sent into an automatic box sealing machine by operators for sealing, so that the products are packaged and encapsulated. Meanwhile, when products of different types and specifications need to be packaged by adopting different types of cartons, a manufacturer can correspondingly arrange a plurality of stations, and each station is respectively provided with a box opening machine and a conveying belt, so that each box opening machine can respectively convey different types of cartons to corresponding packaging stations, and misloading among different stations is avoided.

However, in the actual production process, the packing speed of operators is far slower than the unpacking speed of equipment, so that the automatic unpacking machine can be in a stagnation waiting state for a long time, thereby greatly reducing the utilization rate of the unpacking machine and causing the waste of resources. If a single automatic box opening machine is utilized to pack various different types of cartons at the same time, a separate packaging personnel is required to put various cartons into the automatic box opening machine, and the cartons after box opening are distributed, so that the labor cost is increased. On the other hand, because the automatic carton unpacking machine and the automatic carton sealing machine can only package cartons of specified specifications after debugging, when the sizes of cartons of different specifications are different, packaging parts in the equipment are required to be repositioned and debugged by subpackaging personnel according to the sizes of the cartons, so that the replacement difficulty of cartons of different specifications is further increased.

In addition, the product can also use the cardboard box baffle in the boxing process, the appearance of the cardboard box baffle is generally crisscross or groined, and the cardboard box baffle is formed by mutually splicing a plurality of baffle monomers through seams. The existing method for placing the carton partition boards is divided into two types, wherein when the carton partition boards are made of paper, manufacturers directly place the carton partition boards into cartons after splicing the carton partition boards, so that the carton partition boards are sent together with the cartons after being folded into sheets. When the material of the carton partition plate is hard material such as plastic, nylon and the like, the carton partition plate cannot be folded together with the carton, so that the carton partition plate needs to be transported in batches in the form of the partition plate monomer during sending, and when in boxing, operators splice the corresponding partition plate monomer each time and put the partition plate monomer into the carton together with products. However, the mode of manually placing the boards on site inevitably prolongs the integral boxing time of the boards, so that the boxing efficiency of the production line is reduced, and the economic pursuit of manufacturers cannot be met. On the other hand, along with the gradual increase of the requirement of the current production line on the automation degree, the way of manually completing boxing by a machine is more common, and currently, the existing manufacturers utilize a mechanical arm to replace personnel to complete the placement of products. However, for the cardboard box partition board made of hard materials, the cardboard box partition board needs to be spliced before being packaged, and the action cannot be generally finished only by a mechanical arm; the manufacturer needs to correspondingly add a station for manually splicing the carton partition plates, namely, the splicing action of the carton partition plates is finished manually, and then the subsequent plate releasing action is finished by using a mechanical arm, so that the full automation of the whole boxing flow cannot be realized.

Therefore, the existing carton opening and closing device cannot realize the opening and closing, split charging and board placing work of cartons with various different specifications.

after the top block 14 is separated from the tooth-shaped groove 12, the elastic plate 16 applies a rebound force to the telescopic piece 13, so that the top block 14 can be buckled with the tooth-shaped groove 12 again at the next buckling position; under the cooperation, the extension length of the telescopic piece 13 can be larger than the thickness of each partition plate monomer, so that after each partition plate monomer is pulled out, the subsequent partition plate monomers can be pressed in place under the pushing action, and the mutual dislocation of the partition plate monomers and the taking-out opening 8 caused by the fact that translation is not in place is avoided; meanwhile, through the friction resistance applied to the driving rod 11 and the matching action of the jacking block 14, the jacking block 14 can not apply pretightening force to the driving rod 11 when the telescopic piece 13 is in a contracted state, so that the problem of clamping stagnation caused by overlarge extrusion force when the separator is ejected or extracted is avoided, and the action stability of the separator is improved; in addition, because the telescopic length of the telescopic piece 13 exceeds the moving length of the driving rod 11 each time and the length of one tooth-shaped groove 12, the length of the tooth-shaped groove 12 and the moving length of the driving rod 11 are not related with each other under the action, and therefore, manufacturers can increase the length of the tooth-shaped groove 12 in design, namely, the driving stability and the pressing effect of the driving rod 11 are improved;

C3. the manipulator 3 returns to the high position after grabbing, and then rotates by 90 degrees to the position above another designated plate placing groove 7;

C4. the other ejection column 9 of the plate placing groove 7 ejects the single baffle plate, and the mechanical arm 3 drives the single baffle plate to descend to a low position, so that the inserted joints in the middle of the two single baffle plate are mutually buckled under extrusion to form a carton baffle plate;

C5. the manipulator 3 returns to the high position after the carton partition plates are buckled and rotates for 90 degrees to the upper part of the carton, then falls down to put the carton partition plates into the carton, and when the manipulator 3 descends in place, the carton partition plates are completely buckled under the extrusion of the bottom of the carton and the manipulator 3.

The working principle of the invention is as follows: according to the carton unpacking and conveying mechanism, the unpacking machine 1 can be driven to unpack cartons of corresponding specifications according to the number of cartons on different waiting roller tables 28, and cartons of different specifications are conveyed in place after unpacking by utilizing the cooperation of the conveying roller tables 27 and the transverse moving seat 30, so that cartons of corresponding specifications can be packed by different packing stations, the packing efficiency of operators is improved, and the problem of misloading is avoided. Through the optimization to putting the plate structure, make it can also be to the baffle monomer that is in the state of stacking to take and amalgamate to put the carton baffle after amalgamation into the carton. Under the cooperation, the carton opening and closing device can be used for simultaneously opening, placing and sealing a plurality of cartons with different specifications, and compared with the existing multi-station carton opening and closing device, the carton opening and closing device can effectively reduce the number of carton opening machines 1 and carton sealing machines 2 and realize the effect of full-process automatic operation.

When the sizes of the cartons with different specifications are different, the height of the fixed guide rail 23 and the height of the sliding guide rail 24 can be synchronously adjusted through the matching of the placing frame 20, and the height of the upper limit plate 26 is matched and adjusted, so that the heights of the bottom surfaces of the cartons after bottom sealing can be kept uniform; through the matching arrangement of the fixed guide rail 23 and the upright post 36, the transverse position of the fixed guide rail 23 on the placement frame 20 can be kept unchanged, and one end of different cartons after being installed is limited; under the cooperation, the carton unpacking machine 1 can realize unpacking of cartons with different sizes only by adjusting the interval between the carton pressing rod and the second conveying belt and the opening interval of the second conveying belt. Similarly, through the position control of the packaging frame and the third conveying belt in the case sealer 2, the case sealer 2 can realize case sealing of cartons with different sizes through adjustment, so that the opening and closing stability of the invention is ensured.
